the only reason I can think of for the breakage is that maybe when you pull it back to braid it that area (temple area) is more exposed. So when you leep on it it's getting more contact and friction when you move around in your sleep. That might contribute to the breakage but I don't know for sure. Just a shot in the dark for me.
